Abstract

Organosilicon compounds are prepared by the addition reaction of a gaseous unsaturated hydrocarbon with a silane or siloxane containing at least one silicon-bonded hydrogen atom in the presence of a hydrosilylation catalyst in a liquid reaction medium. In this process the unsaturated hydrocarbon and optionally the silane or siloxane is dispersed into the liquid reaction medium by a jet eductor (also known as a venturi pump) device and the resultant gas-in-liquid dispersion is introduced into a bubble reactor.
